New package needed on Nuget?

I am looking at the .dlls and noticed that they are using "2.9.4.1" yet I getting these errors from the example

Error 1 The type 'Lucene.Net.Analysis.Analyzer' is defined in an assembly that is not referenced. You must add a reference to assembly 'Lucene.Net, Version=2.9.2.2, Culture=neutral, PublicKeyToken=null'.
Error 2 The type 'Lucene.Net.Documents.Document' is defined in an assembly that is not referenced. You must add a reference to assembly 'Lucene.Net, Version=2.9.2.2, Culture=neutral, PublicKeyToken=null'.

So not sure if there are some wrong versions here or what.

The package is also seems to be using "Lucene" what seemed to be deprecated and they say to use "Lucene.net"
